This is a guest post from Mike Montemorra, who is a technology guru with long and successful career in computer industry. Mike keeps an eye on the latest developments in computer and storage technology and publishes his observations weekly. Below is his brief summary of what was important in the past week.
What did we learn last week?
Well, the week has passed rapidly and the days are a bit longer for us here in the US, but it is not feeling like spring quite yet. My bike is slowly rusting in the garage! I thought the groundhog saw his shadow the other day, but it looks like he was wrong and is probably comfortably back inside his burrow by now.
Enjoy these snippets from the week’s news:
It looks like Showa Denko has delivered their MAMR media technology That should enable Toshiba to achieve 2TB/D (18TB on their 9D platform in CY19). It’s nice to see ‘energy assist recording’ working on both aluminum and glass substrates as that should expand market options somewhat for those cost reduced lower platter count drives.
The generation of both structured and unstructured data continues to grow at a 30% + CAGR, meaning we will be entering the zettabyte 10^21 bytes) regime shortly. Here’s the Storage Newsletter post, but you have to pay $$$ for the actual IDC report.
To underscore the exponential growth of data through the next few years, TSMC is deep into its EUV process development for 7nm and below geometries. They are also going to offer both eMRAM and eRRAM on their 22nm finFET process this year This gets them comparable with other foundries that offer embedded NVM (Samsung and Global Foundries). These capabilities will support the upcoming surge in demand for low power IoT and edge computing devices in coming years.
Intel says they are ready with eMRAM and claim a 10 year data retention at 200C and over 1 million switching cycles! This may not yet be an SRAM or DRAM replacement, but it is certainly improving over earlier MRAM devices although their write switching times continue to look problematic.
… and to underscore the potential for cloud growth with 5G and all, ARM is expanding their support for IoT and edge computing with this NEO device roadmap. This is an aggressive roadmap, with the promise of >30% performance improvement generationally… I wonder which one of these upcoming products will include eMRAM…
Wow…surface spin! Another form of electron spin recently discovered on the surface of topological insulating materials like bismuth sulfide (Bi2S3). These spins look controllable and are solidly in the research phase as their properties are being better understood. I don’t see memory applications for this (right now), but there are plenty of other possible applications.
It’s been a decade of Samsung Galaxy phone releases… and it looks like the upcoming Galaxy X will not disappoint. It is 5G capable, can record 1080 quality video at 240fps, has an FM radio, a 3.5″ phone jack, 3.4A-H battery and lots of interesting goodies for a ~$1k pricetag.
All those 10-16MP cameras are going to require a lot of storage (both local and in the cloud) and it appears they eventually (not yet per these specs) will offer a high end model with 1TB of eUFS internal storage.
Since qbits can assume both a ‘0’ and a ‘1’ state simultaneously, did you ever wonder how quantum communication could ever occur? Here is a decent explanation about how classical bits and quantum qubits can be used together to form a unique communication network, with more detail here. These networks are already being built here, China and elsewhere.
Here’s an interesting report by ProofPoint on the distribution of malware. You can download the full report here and it is worth reading through.
… and finally, some management tips that have dawned on myself and apparently a lot of others over the years.
